Napoli only has a minor injury concern ahead of its must-win clash against Juventus on Friday at the Stadio San Paolo.

Alessandro Gamberini will be assessed before the game, which means Miguel Britos may deputize for the 31-year-old. The Partenopei have been struggling in recent weeks, and Giandonmenico Mesto and Pablo Armero may be left out of the lineup for Christian Maggio and Juan Zuniga as manager Walter Mazzarri looks for a winning combination.

Meanwhile, Antonio Conte can field a full-strength side with Giorgio Chiellini returning to the fray after being out since December.

Paolo De Ceglie, Nicklas Bendtner and Simone Pepe are all unavailable, while Nicolas Anelka and Martin Caceres did not train on Wednesday because of back pain.
